Changing the rear main seal

Postby bourbondrnker » Sat Jan 13, 2018 12:33 am

My 1967 has a leak in between the motor and the transmission. I think it's the rear main seal. Does any one have a video link or insight in how to change this out? Any advice or helpful hints are appreciate.

Thank you very much.

360 and sure it's the original transmission.

Auto or stick? It could also be your front pump seal - my C6 leaks from the bellhousing. Check the fluid it drops to see if it's engine oil or transmission fluid. Either way, something has to come out to fix it, but it might save you the hassle of buying the wrong part.

Edit - just saw your other post about your clutch. Forget everything I just said :doh:

Pan off rear main cap off the crank. Push and roll out the top seal then roll in the new seal. Set the new seal in the cap bolt her back up and torque it then side seals and brad pins. Pan gasket and off. IT's not crazy hard just takes time. 2wd you'll have to lift the engine to get the pan off. :thup:

Make sure it's not leaking from the back of the intake or the valve covers.
